[PR3] selectfield getValues issue

If the "value" config is passed to a selectfield, "getValue()" does not call the specified "getValue" function defined in Ext.field.Select (on line 49921 in sencha-touch-all-debug), but the optimizedGetter function (line 3285).

Maybe it's an even bigger problem for other fields or components, too.

I too can reproduce the problem. See below on a snippet of my code on how I "worked" around the problem on PR3. on PR2 it works fine. If I don't set a default value then getValue(), works fine. Its only then you set a value you get returned a object which you have to go into. Unless I'm doing this wrong and its working by chance 100% of the time :-)

I had the same issue with a sliderfield.
As a workaround, I set the value using the setValue function instead of setting it through the config.

I'm guessing the issue happens because of automatic getter and setter functions set on each config, but I'm not sure as I don't know how that works.
If that's indeed the case, it should be fairly easy to fix, by checking if a function already exists with the same name before creating the getter or setter.
